Our glorious documentation for a long time was distributed as a PDF-file, which was nice, but... A bit inconvenient. Especially when pre-stg-2.4 docs were available in form of HTML pages. Once one of the Stg developers mentioned Docbook format which should allow us to make PDF and HTML from a single source. Docbook is an international standard, a special XML-based language for writing technical documentation. Due to its XML nature it can be easily converted into various forms with the power of XSLT. It took a lot of effort for different people to convert old documentation, which source was an ODT document into a Docbook format. It took some effort to write scripts to automate convertion of Docbook into HTML and PDF. But now it is here! Enjoy!
